iPhone 17 Pro Max com bateria de baixa duração e superaquecimento.

Tenho o telefone há apenas três meses e estou a ter problemas com a duração da bateria. Mesmo com uso normal do dia a dia — principalmente redes sociais, mensagens, navegação na internet e outras tarefas básicas — a bateria não dura nem perto de 24 horas.

Isso é particularmente preocupante porque a descrição do produto da Apple afirma que o iPhone 17 Pro Max oferece até 33 horas de reprodução de vídeo. Com base na minha experiência, o desempenho da bateria que estou obtendo está muito aquém do que eu esperaria razoavelmente de um dispositivo dessa idade e com essas especificações.

Outro problema é que o telefone esquenta muito durante o uso normal. Quando verifico a saúde da bateria, ela ainda mostra 100%, então estou preocupado que possa haver um problema subjacente que não esteja sendo refletido na porcentagem de saúde da bateria.

Gostaria que a Apple investigasse isso adequadamente e determinasse se há algum problema de hardware ou software que esteja afetando o desempenho da bateria e causando o superaquecimento. Como o telefone tem apenas três meses de uso, também gostaria de saber sobre a possibilidade de trocá-lo por um do mesmo modelo, pois este não está atendendo às minhas necessidades.

>>iPhone 17 Pro Max: poor battery life and overheating.

I have owned the phone for only three months, and I am experiencing issues with battery life. Even with normal daily use—primarily social media, messaging, web browsing, and other basic tasks—the battery doesn't last anywhere near 24 hours.

This is particularly concerning because Apple's product description states that the iPhone 17 Pro Max offers up to 33 hours of video playback. Based on my experience, the battery performance I am getting falls far short of what I would reasonably expect from a device of this age and with these specifications.

Another issue is that the phone gets very hot during normal use. When I check the battery health, it still shows 100%, so I am concerned there might be an underlying problem that isn't being reflected in the battery health percentage.

I would like Apple to properly investigate this and determine if there is a hardware or software issue affecting battery performance and causing the overheating. Since the phone is only three months old, I would also like to know about the possibility of exchanging it for a unit of the same model, as this one is not meeting my needs.<<

If you think that your battery life is not up to the specifications advertised by Apple, you can contact the official Apple Support about that, they are able to diagnose your iPhone online.

Did you also check which apps are using most of your battery life in Settings -> Battery?

Playing graphic intensive games, using Wi-Fi most of the time and a bright display can also contribute to that shortened battery life. Have a look at the related article:

The measure of battery health deterioration/drainage is subjective and can vary depending on individual usage patterns. There is no universal standard to determine whether the battery health deterioration/drainage is normal or abnormal because it heavily relies on how the battery is used and maintained.

Try to monitor Battery usage by iPhone Activity as shown below

What is shown under battery usage? Checking that would give you an indication of the usage behavior.
